Ingredients

Directions

The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Preheat the oven to 400°F (200°C).

Make the batter

  1. In a bowl, cream the butter and sugar together.

  2. Add the eggs one at a time, mixing well after each addition.

  3. Stir in the flour, baking soda, lemon rind, lemon juice, currants, and cinnamon until combined.

Bake

  1. Drop spoonfuls of the batter onto well-buttered parchment paper in a baking pan.

  2. Bake until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Flour
Forms the structure that holds the cake together as it bakes.
Butter
Creamed with sugar to trap air and add richness and tenderness.
Sugar
Sweetens the cake and helps it brown during baking.
Eggs
Bind the batter and add structure, moisture and lift.
Baking soda
Reacts with the batter's acidity to produce gas that helps the cake rise.
Currants
Add chewy pockets of fruit sweetness that stay distinct in the batter.

The step that matters

Creaming the butter and sugar. Beating the butter and sugar together traps air in the fat, which gives the batter lift and a tender crumb. If the butter is too cold or the mixture is under-beaten, the cake can turn out dense.

Swap the currant
